1,293,226. Specification of Letters Patent. Patented Feb, 4, 1919, Application filed August 26, 1918. Serial No. 251,488.

To all whom it may concern: recess or channel 14 between said cone 12 Be it known that I, HOWARD A. SMOCK, a and flange 11, the channel 14 being utilized citizen of the United States, residing at in performing several of t e important Indianapolis, in the county of Marion and functions of the device as will hereinafter State of Indiana, have invented certain new appear. and useful Improvements in Combined The kerosene is conducted to the device erosene-Converters and Gas-Burners, of througi a conductor pipe 18 which passes which the following is a specification. through a suitable opening in the wall of his invention relates to a device for conthe stove, furnace or boiler, the approxiverting kerosene into gas and for burning mate location of said wall being indicated the gas for heat producing purposes; and by the line AA in Fig. 1. Conductor one of the objects of the invention consists pipe 18 after entering the combustion in the provision of a device of the above chamber extends downwardly into annular character wherein the oil is fed around the channel 14 of the device and is formed into point of combustion and where it is sub a coiled portion 19 which extends around jected to a steady heat produced thereby, so the major circumference of said channel and that the kerosene will be readily converted upwardly in a portion 20 and again out into a gas which is carried outside of the through the wall of the stove, boiler or furstove, furnace or boller and where it is disnace where the free end of the pipe is procharged into a mixer for adding the proper vided with a suitable gas regulating valve amount of air to support proper combus- 21 for controlling the discharge of-gas from tion, the mixture being returned and uniplpc p rti n 20- The nozzle end 22 of valve formly distributed around the burner for 21 is disp s d So as to discharge the gas into producing a highly efficient combustion at a the open end of a pipe 23 through which the minimum consumption of kerosene. V gas is returned to the burner. The diameter further object of the invention consists f pipe 2 is considerably larger than pipe i th r vi i f a d i f converting 20 so that the enlarged orifice in the free kerosene into gas and for burning the ga e nd of the pipe 23 acts as a mixer in admit- V for heat producing purposes, which is exting a1r for promoting proper combustion tremely simple in construction, eflicient in of the gas. Pipe 23 communicates with a its operation, and which is easily install d cone-shaped disk 25 which is arranged over or removed whenrepairs are necessary. the top of inverted cone 12 of base 10, and I accomplish the above objects of th incone-disk 25 is maintained a uniform disvention, and such others as may appear tanceabove the surface of the top of cone from a perusal of the following specification 12 y means of i g a1 g y a and claims, by means of the construction narrow intervening gas discharge passageillustrated in the accompanying drawings, way 27 is provided and which extends forming a part hereof in whicharound the entire circumference of the cones Figure 1 is a top or plan view of my im- 12 and 25 The gas discharged from pipe proved device for converting kerosene into 23 is directed upon the apex of inverted gas and for burning the gas for heat procone 12, and the conical formation of said ducing purposes.

As the converting kerosene into gas and for burndiameter of cone-disk 25 is slightly in excess ing the gas so converted comprises, preferof the diameter of inverted cone 12 the overa 1y, a circular base 10 having an integrall hanging edge of the former will cause the O is an upwardly disposed inverted cone vent premature deterioration of the coiled 12, the object of which will be hereinafter portion 19 of conductor pipe 18 in annular described. The location of inverted cone 12 channel 14, and to prevent too rapid radiaon base 10 provides an intervening annular tion of heat, I embed the coiled portion 19 of conductor pipe 18 in a layer of fire-clay 30, as clearly shown in Fig. 2 of the drawing. Fire-clay 30 is so placed in channel 14 as to leave an annular trough to form .a reservoir for receiving the kerosene initially employed for raising the temperature of the burner to a point to convert the kerosene in the coiled portion 19 of conductor pipe-18 into gas. After the burner is in operation, the annular flame of combustion emerging from intervening gas passageway 27 is constantly directed against fire-clay 30 so as to maintain the latter constantly in a state of incandescence.

The device is so simple that further description is deemed unnecessary, and the burner has met all requirements imposed in numerous prolonged tests.

Having thus fully described my vention, What I desire to secure by Patent, is-

1. A device for converting kerosene into gas and for burning the gas comprising a base, an inverted gas distributer cone arranged centrally on said base, a flange arranged around the outer periphery of the base to provide a channel between the flange and cone, a cone-shaped disk arranged over the top of the inverted cone with an intervening gas discharging passageway, a conductor pipe for conducting the kerosene from outside the device and around in said channel of the device and again outside the device, a valve on the free end of said conductor pipe for controlling the discharge of gas, and a pipe for receiving the gas discharged from the valve and conveying it to and discharging it upon the apex of the gas distributer cone. y

2. A levice for converting kerosene into gas and for burning the gas comprising a circular base, a circular gas distributer cone arranged centrally on said base, a flange extending around the outer marginal edge of the base to form an annular channel besaid in- Letters Oopiesof this patent may be obtained for five cents each, by addressing the tween said flange and cone, a cap arranged sufficiently above the gas distributer cone to provide-an intervening gas discharge passagevvay over the entire surface of said distributer cone, a kerosene conductor pipe arranged around and in the annular channel in the base and extending outside the-device, a valve for controlling the discharge of gas from the conductor pipe, a pipe for receiving the gas discharged from said valve anddischarg-ing it backinto the? gas discharge passageway between the'cone and cap, and a layer of fire-clay arranged Within said annular channel and covering said conductor pipe for retarding the -radiation of heat. 7

- 3. A device for convertingkeroseneinto gas and for burning the gas comprising a circular base, a circular gas -distri buter cone arranged centrally on said base, a flange extending around the outer marginal edge of the base to form an annular channel between said flange and cone, a cap arrangedover the gas distributer cone, means for holding the cap a uniform distance away from the distributer cone to providean intervening gas discharge passageway over the entire surface of said distributer cone, a kerosene conductor pipe arranged around "and in the annular channel inthe' base and-extending outside the device, a valve for controlling the discharge of gas from theeorr ductor pipe, a pipe for receiving the-gas discharged from said'valve and discharging it back into the gas discharge passageway between thecone and cap, and a layer of ire-clay arranged within said annularcha-nnel and coverlng sail conductor pipe for retarding the radiation of'heat.

In Witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this 22nd day of August, A. D. one thousand nine hundred and eighteen,
